DEVICE FOR ELIMINATING ODORS FROM GASES, FUMES, 8w.

Specification of Letters Patent.

Patented J an. 9, 1917.

Application filed April 7, 1913. Serial No. 759,403.

To all whom it may concern Be it known that I, SAMsoN D. EISEN- DRATH, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Devices for Eliminating Odors from Gases, Fumes, &c., ofwhich the following is a specification.

This invention relates to a device for. eliminating odors in certainprocesses of manu facture, and has for its object to provide an improveddevice of this description.

I have illustrated in the drawings certain means for carrying out theprocess.

Figure 1 shows one form of apparatus for this purpose; Fig. 2 showsanother form of apparatus for this purpose; Fig. 3 is an enlarged viewshowing one form of spraying device.

Like numerals refer to like parts throughout the several figures.

This invention is particularly adapted to be used where objectionableodors are produced in treating oils, greases, butter, etc.

Referring to Fig. 1, I have shown a receptacle 1 in which is placed thematerial from which the objectionable odors are discharged. Thisreceptacle is provided with any suitable means for heating it so as toraise it to the temperature desired. Connected with this receptacle is adischarge pipe 2 which is provided with a bend at 3. Beyond the bend 3,I have provided a spraying device 4 which discharges a fine spray ofWater into the pipe 2 so as to bring said water into contact with thegases, fumes or other materials passing through said pipe.

I have illustrated in Fig. 3 a particular construction of sprayingdevice which consists of a rotating part 5 having wings 6, said rotatingpart mounted upon a hollow pipe 7 fastened to a base 8 which is attachedto the discharge pipe 9. When the water is turned on by means of thevalve 10, the retating part 5 is rotated and the wings cause a finespray of water to be discharged into the pipe 2, said spray covering theentire area of the pipe. I also prefer to provide the spraying devicewith a shield 11 which guides the gases, fumes and other materialspassing through the pipe 2 beyond the joint between the part 5 and thepipe 7 so as to prevent corrosion thereof. I also provide a steam pipeconnection 12 for the valve 13 arranged so that steam can also be blowninto the pipe 9 and through the spraying device 4. The pipe 2 connectswith the bottom of the tank 14, said tank being provided with adischarge pipe 15 having a bend 16, there being arranged at this bend, aspraying device 4. I may also provide a suitable spraying device 17 atthe top of tank 14:. The pipe 15 is provided with a connection 18leading to the sewer so that the offensive matter may be discharged intothe sewer. The pipe 15 may be connected to a smoke stack 19. Somesuitable means is provided for removing the gases, fumes, etc. throughthe various pipes. As herein shown I provide a fan 20 for this purpose.The pipe 15 may be provided with any desired number of bends or sprayingdevices so as to insure proper removal of the offensive matter.

In Fig. 2, I have shown a different form of apparatus in which thereceptacle 1 is provided with a discharge pipe 21 which has asubstantially horizontal portion 22, this portion 22 being simplyinclined sufliciently to cause the liquid in the pipe to flow therealongby gravity. I provide in the portion 22 of the pipe, a series ofspraying devices 4 located at sufficient intervals, there being enoughof these spraying devices to remove the ofiensive matter. The portion 22of the pipe is provided with the man holes 23 by means of which accessto the spraying devices may be had. The portion 22 of the pipe isprovided with a suitable connection 24: to the sewer or other dischargepoint, and the water and offensive matter passes through the connections25 into said pipe. This construction is also provided with afan 20 forcausing the proper removal of the gases, fumes, etc.

It will be seen that by means of this invention, the current of gases.fumes, etc. is successively sprayed at different points along its lengthso as to remove therefrom the objectionable matter and that theremaining portion is discharged into the air free from suchobjectionable matter, the water and objectionable matter beingdischarged into the sewer or at any other desired point.

I have illustrated a fan as producing the draft or current through thepipe but it is of course evident that the air may be blown in throughthe material if desired. It will be noted that the spray is injectedinto the current or draft in the same direction the current is travelingand therefore does not produce any back pressure or interfere with thecurrent. This permits gases and other matter to pass off as freely as inan ordinary pipe, and in fact increases the draft because 'the spraycondensessome of the material.

This spray also separates the solid particles from the gas, the gaspassing out the chimney in a purified condition, the solid matter andother objectionable matter being precipitated and discharged into thesewer. This construction permits great efiectiveness and at the sametime a low cost of installasaid pipe located in the path of the gasespassln-g through the pipe and a shield suspended in front ofsaidspraying device.

3. A device for eliminating odors from.

shaped bend, a. shield in front of said spraying device and meansseparate from said spraying device for causingthe gas to flow throughsaid connection.

In testimony whereof, I a'fiix my signature in the presence oftwo,witnesses-this 24th day of March 1913. V V
